We observed 7 INTEGRAL sources with the Chandra X-ray Observatory to refinetheir localization to ~2 arcsec and to study their X-ray spectra. Two sourcesare inferred to have a Galactic origin: IGR J08390-4833 is most likely amagnetic cataclysmic variable with a white dwarf spin period ~1,450 s; and IGRJ21343+4738 is a high-mass X-ray binary. Five sources (IGR J02466-4222, IGRJ09522-6231, IGR J14493-5534, IGR J14561-3738, and IGR J23523+5844) prove to beAGN with significant intrinsic X-ray absorption along the line of sight. Theirredshifts and hard X-ray (17-60 keV) luminosities range from 0.025 to 0.25 andfrom ~2x10^43 to ~2x10^45 erg/s, respectively, with the distance to IGRJ14493-5534 remaining unknown. The sources IGR J02466-4222 and IGR J14561-3738are likely Compton-thick AGN with absorption column densities NH>10^24 cm^-2,and the former further appears to be one of the nearest X-ray bright,optically-normal galaxies. With the newly-identified sources, the number ofheavily-obscured (NH>10^24 cm^-2) AGN detected by INTEGRAL has increased to~10. Therefore, such objects constitute 10-15% of hard X-ray bright, non-blazarAGN in the local Universe. The small ratio (<<1%) of soft (0.5-8.0 keV) to hard(17-60 keV) band fluxes (Chandra to INTEGRAL) and the non-detection of opticalnarrow-line emission in some of the Compton-thick AGN in our sample suggeststhat there is a new class of objects in which the central massive black holemay be surrounded by a geometrically-thick dusty torus with a narrow ionizationcone.
